Complete Omni Cell For Liquids - Sealed

Highlights

• Sealed Liquid Cells
• Demountable Liquid Cells
• Mull Cells
• Quick release clamping mechanism
• Wide choice of window materials
• Wide choice of pathlength

The Omni-Cell System is a novel approach to the analysis of liquid samples in transmission spectroscopy - one cell is suitable for all applicaitons. The demountable version is a gerneral-purpose cell for all liquids. It has the advantage of being easy to dismantle for cleaning, and for changing windows and spacers.

The cells are compatible wlith all FTIR Spectrometers, as well as older dispersive systems. They can be configured easily for use as demountable liquid cells, permanently sealed liquid cells, or as mull cells.

Transmission is well established as a technique for analyzing smaples in infrared. The choice of window material, pathlength, and window configuration are determined by the sample and wavelength range of interest.

Samples can be analyzed neat or diluted with an appropriate solvent. FOr quantitive analysis, the sample is often analyzed in a cell with a known pathlength. A guide to the selection of the correct pathlength for various concentration is shown opposite.

Solid samples can be analyzed using the mull technique. The solid is mixed with a mulling agent, such as Nujol, to form a mull. The mull is then analyzed between circular windows.
